\AUTOMATIC FAN.

Application filed August 1a, 1915. Serial No. 45,337.

To all whom it may concern:

Be it known that I, WLADYSLAW MATU- SIEWICZ, a subject of the Czar of Russla, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have 1nvented certain new and useful Improvements in Automatic Fans, of which the following is a specification.

This invention relates to certain new and useful improvements in automatic fans.

An object of the invention is to provlde a fan attachment for rocking chairs in which the rocking movement of the chair is converted into power whereby the fan is operated to create a draft.

A further object of the invention is to provide a fan attachment for rocking chairs in which the fans and operating mechanism therefor are constructed independently of the chair and may be readily attached thereto in operative position so that the rocking movement of the chair will be converted into energy for operating the fans.

With these general objects in View and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in' the accompanying drawings, and pointed out in the claim.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several Views:Figure 1 is a side elevational view of a chair and fan attachment therefor built in accordance,

with the present invention. Fig. 2 is a horizontal sectional view taken on line II-II of Fig. 1, with the chair bottom and back re' moved, better to illustrate the operating mechanism. Fig. 3 is a sectional view of a portion of the operating mechanism illustrating the manner of driving the same. Fig. 4 is a detailed sectional View of a portion of one of the driving pulleys and the supporting axle therefor, withthe ratchet cap in operative position, and, Figs. 5 and 6 are side elevational and sectional views respectively,' of the power pulley with the ratchet cap removed.

Briefly described, the present inventionaims to provide a fan attachment for rocking chairs in which a rocking chair of usual construction may be provided with the present form of fan attachment. The fans are carried by the upper side edges of the chair back while the operating mechanism therefor is located between the chair bottom and the rockers and by pawl and ratchet'mechanism, the fans are'caused to be driven in a continuous direction while the operating chair rocks forward and backward. A base supporting frame is provided for the rocking chair and includes cushion springs engaging the chair rockers adjacent each end which Will assist the rockin movement of the chair and also the drivmg mechanism for the fans.

Referring more in detail to the accompanying drawings, the reference numeral 10 designates in general arocking chair in cluding'a bottom or seat portion 11, supporting legs 12 supported at their lower ends on rockers 13 while rungs 14 of the usual form connect the legs of the chair. A back portion 15 is carried by the chair seat 11 and has laterally projecting from the upper side edges thereof opposite stub shafts 16 that may be supported thereon in any suitable manner, while fan wheels 17 are Patented May so, rare.

carried by." the outer ends of the shafts 16 and .fiXed theretoin any suitable manner.

A. base supporting frame is provided for the chair and upon which the rockers 13 are adapted to rest, the same including a pair of side rails orfeet 18 arranged parallel with the adjacent rocker 13, the feet 18 being connected to the rockers 13 at points intermediate the ends thereof as by links 19. Compression coil springs 20 are suitably secured at their lower ends to the feet 18 while transverse bar 21 while the rear ends thereof are connected by the transverse bar 22.

-The operating mechanism for the "fan wheels 17 is located between the chair bot tom 11 and the. rockers 13, this mechanism being more clearly shown in Figs. 2 "to 6 and includes a rectangularframe embody.-

ing front and rear bars 23 and 24 connected by end or side bars 25. The front bar 23 rests upon the rungs 14 and also engages the front legs 12 of the chair while the rear end of the frame is supported in a position elevated from the rear end of the rungs 14 by the rearwardly. positioned standards 26 engaging'at their lower ends as at 27, the rockers 13, while the upper ends thereof are connected in any suitable manner to the rear frame bar 24. The mechanism supporting frame is further provided with a series of spaced bars 28, 29, 30 and 31, all arranged in parallelism and extending between the bars 23 and 24. Transversely positioned shafts 32 and 33 are journaled respectively on the upper and lower sides of the bars 28 to'31 and in different axial planes, the shaft 33 being positioned rearwardly of the shaft 32 as is clearly indicated in Fig. 3. Each of the shafts 32 and 33 has fixed thereto intermediate the bars 29 and 30, lantern gears 34 and 35 suitably spaced apart to provide a clearance for the restricted passage of the rack bar 36 provided with teeth 37 on opposite sides thereof and hingedly connected at its lower end as at 38 to the transverse connecting bar 21 as clearly shown in Fig. 2, it being noted that the upper end of the rack bar 36 is' freely positioned so that the same may readily swing on its lower pivot point 38 when the chair is given a rocking movement.

A driven pulle 39 is loosely journaled on each of the sha ts 32 and 33 between the bars 2829 and 30-31. A detailed showing of the pulley is disclosed in Figs. 4, 5 and 6 and includes a hub portion 40 provided with a side opening 41 in which is mounted a spring 42 adapted to engage the pawl 43 mounted on the pin 44 positioned transversely of the, opening as is indicated in Figs. 5 and 6. A ratchet cap 45 is mounted on the shafts 32 and 33 and keyed thereto as at 46, the said cap being provided with a plurality of circularly arranged ratchet openings 47 in which the pawl 43 is adapted to be received and escape.

It will be understood that the pawls 43 carried by the power pulleys 39 operate in opposite directions in view of the fact that the opposite faces of the rack bar 36 cause the same to be moved so as to impart a continuous rotary motion in one direction to the fan wheels 17.

The rear ends of the end or side bars 25 and the bars 28 to 31 are ,provided with alinedjournal bearings 48 in which is journaled a shaft 49 projecting laterally of the side bars 25 and carrying on the projecting ends thereof the sheave blocks 50. The shaft 49 has fixed thereto'intermediate the bars 28-29 and 30-31 and-in alinement with the power pulleys 39 smaller pulleys 51 which communicate with the connecting belts 52.

The stub shafts 16 carried by the chair back for supporting the fans 17 have fixed thereto in any suitable manner, sheave blocks 53 that communicate with the lower sheave power pulleys by the blocks 50 by the connecting cords or cables 54.

From the above detailed description of the invention, it is believed that the operation thereof will be readily apparent, it being noted that the springs 20 tend to normally hold the chair 10 in an upright position but it also assists in the rocking movement of the chair to compensate for any excess friction of the driving mechanism. During the rocking movement of the chair, the lantern gears 34' and 35 mounted on the shafts 32 and 33 are moved over the double rack bar 36 and cause the shafts 32 and 33 to be continually revolved in a like direction by the oppositely-directed pawls 43 carried by the driving pulleys 39. When the forward edge of the chair is lowered during rocking movement, one of the ratchet caps 45 will positively engage the pawl 43 and drive the supporting pulley therefor, and during this movement the other ratchet cap escapes over the other pawl. When the forward end of the chair is elevated, the momentum added to the driven pulley will permit the same to continuously revolve with the result that the pawl carried thereby will escape over the adjacent ratchet cap, and during this movement the opposite pawl and ratchet mechanism will be effective. This continuous movement in the same direction of the pulleys 39 is communicated by the belts 52 to the shaft 49 and by the coiiperating sheaves 50 and 53 and the connecting cable 54 to the fans 17. v

A serviceable automatic fan is hereby provided that primarily includes an attachment for rocking chairs ofthe usual construction, the same embodying few working parts, which are extremely simple in construction and inexpensive to manufacture, and which may be readily replaced when injured or otherwise broken.

While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that various forms, modifications and arrangements of the parts may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is A fan attachment for chairs including a chair having fan wheels journaled to the upper side edges of the back thereof, a rectangular frame mounted on the chair between the seat and rockers, a pair of shafts journaled transversely of the frame, lantern gears fixed to said shafts, pulleys loosely mounted on said shafts, spring-pressed pawls carried by said pulleys, ratchet caps fixed to said shafts and operatively posi tioned with respect to said pawls, a base supportmg frame for the rockers, link connections between the side rails of the supshaft carried by said rectangular frame ad-- jacent the rear end thereof, connecting belts between said loosely-mounted pulleys and driven shaft, and driving connections between said driven shaft and fan-supporting shafts.

In testimony whereof I afiix my signature.
